Abstract
A high performance full scalable video codec called embedded multiresolution motion-compensated three-dimensional SPIHT (EM-MC-3DSPIHT) is presented. By combining the bit allocation of motion vector and the scalable spatio-temporal orientation wavelet tree with the EM-MC-3DSPIHT algorithm, it not only provides a full scalable decoding, but also significantly improves the rate-distortion (RD) performance compared with that of Kim et al's codec (see IEEE Trans. on Circuit and Syst. Video Tech., vol.10, p.1374-87, Dec. 2000), particularly at low bit rates. Simulations show that the proposed video codec provides performance not only better than that of MPEG-2 at medium to high bit rates but also comparable to H.263 at low bit rates.
